Research and Communication Skills
Organizing a research paper
Decide up front what the point of your
paper is and stay focused as you write
Once you have decided on the main point,
pick a title
Start with an outline
Use multiple levels of headings (usually 2
or 3)
Don’t ramble!

Research and Communication Skills
Typical paper organization
 Abstract
 Short summary of paper
 Introduction
 Motivation (why this work is interesting/important, not your personal
motivation)
 Background and related work
 Sometimes part of introduction, sometimes two sections
 Methods
 What you did
 In a systems paper you may have system design and evaluation sections instead
 Results
 What you found out
 Discussion
 Sometimes called Conclusion
 May include conclusions, future work, discussion of implications,etc.
 References
 Appendix
 Stuff not essential to understanding the paper, but useful, especially to those
trying to reproduce your results - data tables, proofs, survey forms, etc.

Research and Communication Skills
Road map
 Papers longer than a few pages should
have a “road map” so readers know where
you are going
 Road map usually comes at the end of the introduction
 Tell them what you are going to say, then say it, (and
then tell them what you said)
 Examples
 In the next section I introduce X and discuss related work. In
Section 3 I describe my research methodology. In Section 4 I
present results. In Section 5 I present conclusions and possible
directions for future work.
 Waldman et al, 2001: “This article presents an architecture for
robust Web publishing systems. We describe nine design goals for
such systems, review several existing systems, and take an indepth look at Publius, a system that meets these design goals.”

Research and Communication Skills
Use topic sentences
 (Almost) every paragraph should have a topic
sentence
Usually the first sentence
Sometimes the last sentence
Topic sentence gives the main point of the paragraph
 First paragraph of each section and subsection
should give the main point of that section
 Examples from Waldman et al, 2001
In this section we attempt to abstract the particular
implementation details and describe the underlying
components and architecture of a censorshipresistant system.
Anonymous publications have been used to help bring
about change throughout history.

Research and Communication Skills
Avoid unsubstantiated claims
 Provide evidence for every claim you make
Related work
Results of your own experiments
 Conclusions should not come as a surprise
Analysis of related work, experimental results, etc.
should support your conclusions
Conclusions should summarize, highlight, show
relationships, raise questions for future work
Don’t introduce new ideas in discussion or conclusion
section (other than ideas for related work)
Don’t reach conclusions not supported by the rest of
your paper

Research and Communication Skills
Plan your talk
 Make an outline of what you want to talk about
 No need to present every detail of your paper
Your presentation should motivate people who find it
interesting to read your paper
 Consider the background of your audience
If they are experts, focus on the details of your
research and results
If they are not experts, spend time on background
and motivating the problem
 Consider how much time you have (10 minutes
MAXIMUM + 5 minutes for questions)

Research and Communication Skills
Structure your talk
 Outline
 Optional for short talks
 Background and motivation
 Sometimes you may want to lead with this
 Research methodology
 Or system design + evaluation
 Results
 You may not have them if this is a work in progress
 Related work
 Could also go after background or at end, optional for short talks
 Contributions
 Useful in job talk, probably no time in 10-minute talk
 Future work
 Optional for short talks

Research and Communication Skills
Making slides
 Use easy-to-read fonts
 Avoid text < 20 pt font
 Use a simple slide design, no distracting background
images
 Use a color scheme with high contrast
 Avoid animation unless it helps illustrate your point
 Clipart can help make your points more clear and/or
memorable, but don’t let it distract
 Make figures and tables readable
 Don’t make too many slides (1-3 minutes/slide)

Research and Communication Skills
Slide content
 Are slides lecture notes/handouts?
 For a class or tutorial, slides may double as lecture notes 
more content on slides
 For a research presentation, your paper is usually the “handout”
 less content on slides
 Don’t try to put everything on the slide
 Don’t include text unless you want people to read it
 If people are reading your slides they are not listening to
you
 Keep text short
 Don’t put too much math on a slide
 Just include key points, examples, etc.
 A figure may be worth 1000 words

Research and Communication Skills
If you use overhead projector
White background usually best
Don’t use a paper to cover up part of your
slide and uncover as you go
If you have to skip slides, don’t put them
up and take them down real fast, just skip
them

Research and Communication Skills
Prepare
 Make your slides in advance
 Practice
Time yourself
Get feedback from others
Watch yourself on video
 Make sure you know how to hook your laptop up
to the projector, change screen resolution,
advance your slides, etc. (Mac users, bring your
adaptor!)
 If you need to point to parts of your slides,
decide if you will use, mouse, stick, laser
pointer, etc. and bring it with you

Giving your talk
 Dress neatly
 Stand up straight, hands out of pockets
 Don’t hide behind the podium
 Move around, but not too much
 Keep track of time
 Put your watch on podium, note clock in room, watch moderator
with time cards, etc.
 Face the audience, look at your audience, not just one
person
 Project your voice
 Don’t talk too fast
 Finish on time (or early!)

Keeping your audience engaged
 Convey enthusiasm
 Inject humor
 Tell a story
 Ask the audience questions
 Modulate your voice
 Speak slowly
 Try to prevent your audience from getting lost
Provide ample background
Define important terms up front
Don’t get into highly technical details unless that’s
what your audience expects

Research and Communication Skills
Handling questions
If you have a strict time limit,
leave time for questions or avoid
taking them
Answer clarification questions quickly
Suggest that questions that will require
lengthy answers be taken off line
Don’t get flustered by critics or questions
you don’t know the answer to
Stay calm, diffuse the question, keep going
